line n+1, information for n vehiclesThere is a space between two positive integers x,y,x and y per lineX is the coordinates of the car, y is the speed of the car0Output: Total number of overtaking "in reverse order"　　　First of all, the first time I didn't read. Test instructions: Open a structure, according to the coordinates from small to large sort record the order, then sort by speed, with the total minus each position, and then accumulate. Later

The problem is described as follows: There are 250 million integers (these 250 million integers are stored in an array, and the array is placed in external memory or memory, without further specific instructions); Ask to find out the number of numbers that are not duplicated in these 250 million numbers; In addition, the available memory is limited to 600M; Require the algorithm to be as efficient and opt
